Fuddruckers is using a mobile site, a QR code and SMS to solicit fast customer feedback for the restaurant chain. Informational table tents at each table provide easy instructions on how customers can complete a brief service survey using their smartphones. “Restaurant chains like Fuddruckers will receive more feedback with mobile than traditional paper or Web feedback forms, and the feedback is immediate and actionable,” said Ken Kimmel, president of On The Spot Systems, which worked with Fuddruckers on the feedback initiative.
